mips andersonwrote a review of KEEN Voyageur Mid Hiking Boot - Men's on May 4, 2010
As others have noted these are more shoes than boots. However, I'm going back for another pair as I've worn out the pair I bought a 16 months ago. These shoes rock! I bought the size that I would normally and they fit great.
Pros: excellent fit, construction, design, does what it is designed for
Cons: not waterproof, not for colder temps (nor do they claim either)
They had an easy break in period, and quickly became my primary day to day shoe. The have excellent grip, look good, clean easily, don't mark up floors easily, have excellent wear resistance (both inside and out), dry pretty fast, and are light weight for their class. And they last. I'm not tromping around with weapons and ammo in Afghanistan, but I put mine to the test just about every day.
I'm familiar with many different boots and shoes having sold them for a few years, and I'm going back to get another pair of these.
